It is not only easy to assemble and maintain, but also greatly reduces the overall volume, making the docking station more compact and lightweight, suitable for desktop use, and does not take up too much space. Through the design of the output switching module and its docking module, the docking station can intelligently switch the electrical signal connection between the first connection unit and the second connection unit. This design allows users to flexibly choose to connect different devices or power cords according to actual needs, without frequently changing physical interfaces or carrying multiple expansion devices. In addition, the application of gallium nitride materials, due to its high efficiency and low heat generation characteristics, further improves the charging efficiency and safety, and meets the needs of fast charging of various devices.

At the same time, the application of the displacement sensor (step S3) ensures the accurate verification of the bidirectional connector and the contact connector in the X-axis travel, further ensuring the reliability and stability of the connection. Furthermore, the real-time acquisition function in step S4 covers multi-dimensional data such as the zero-voltage switching waveform integrity of the GaN switch array, the multi-channel current distribution deviation value, and the temperature rise gradient of the graphene thermal conductive layer surface, providing strong support for the comprehensive evaluation of the electrical characteristics and thermodynamic performance of the docking station. Finally, when evaluating the overall performance of the system (step S5), by performing multiple rounds of plug-in durability stress tests, waveform stability tests under asymmetric load conditions, and self-recovery ability tests under sudden surge interference, the solution not only verifies the mechanical life and electrical stability of the docking station, but also ensures its reliable operation in complex environments.

In this embodiment, a high degree of integration is achieved through the precisely designed structure of the housing 1 and the inner bracket 2. The design of the cavity 21 in the inner bracket 2 not only effectively utilizes the limited space, but also ensures the orderly arrangement of various functional modules (such as the main control module 5, the interactive module 6, the connection unit, etc.) through the rectangular cross-sectional shape and the division of the four fixing areas. It is not only easy to assemble and maintain, but also greatly reduces the overall volume, making the docking station more compact and lightweight, suitable for desktop use, and does not take up too much space. Through the design of the output switching module 9 and its docking module 91, the docking station can intelligently switch the electrical signal connection between the first connection unit 7 and the second connection unit 8. This design allows users to flexibly choose to connect different devices or power cords according to actual needs, without frequently changing physical interfaces or carrying multiple expansion devices. In addition, the application of gallium nitride materials, due to their high efficiency and low heat generation characteristics, further improves the charging efficiency and safety, and meets the needs of fast charging of various devices.

[0030] In the above embodiment, the interactive module 6 is directly exposed to the outside of the housing 1 through an interactive interface, which greatly improves the convenience of user operation. The user can directly perform operation settings, status viewing and other functions through an intuitive interface without opening the device or relying on additional software tools. This instant feedback mechanism not only simplifies the operation process, but also enhances the user experience, making the docking station more intelligent and user-friendly. The present invention adopts a modular design, and key components such as the main control module 5, the interactive module 6 and the connection unit can be installed and disassembled relatively independently. This design facilitates users to upgrade or replace modules according to actual needs, prolongs the service life of the product, and also reduces maintenance costs.

[0031] The bottom of the shell 1 is provided with a shock-absorbing and anti-skid pad 12. The shell 1 is formed by extrusion of a rectangular aluminum alloy profile. The inner wall of the placement cavity 11 is provided with an assembly positioning slide 13. The outer wall of the inner bracket 2 is provided with an assembly positioning slide bar 25. The assembly positioning slide bar 25 is used to cooperate with the assembly positioning slide 13 to slide the inner bracket 2 into the placement cavity 11. In this embodiment, the shock-absorbing and anti-skid pad 12 at the bottom of the shell 1 not only enhances the stability of the docking station during use, effectively prevents sliding or tipping caused by accidental touch or uneven desktop, but also protects the internal electronic components from external vibration through its shock-absorbing performance, thereby extending the service life of the device. The shell 1 itself is formed by extrusion of a rectangular aluminum alloy profile. This material selection not only gives the docking station a sturdy and durable characteristic, but also ensures good heat dissipation performance, which helps the gallium nitride charger maintain a stable operating temperature at high power output, thereby improving overall safety and reliability. The assembly positioning groove 13 provided on the inner wall of the placement cavity 11 cooperates with the assembly positioning slide bar 25 on the outer wall of the inner bracket 2, so as to realize the precise sliding fit of the inner bracket 2 in the placement cavity 11. This design not only simplifies the installation and removal process of the inner bracket 2 and improves the assembly efficiency, but also ensures the stability of the inner bracket 2 during use and avoids the problem of poor contact or damage caused by looseness.

[0032] The bottom surface of the placement cavity 11 is provided with a threaded connection column 111, and the fourth fixing area 25 is provided with a threaded countersunk hole 251, and a screw is passed through the threaded countersunk hole 251 to connect with the threaded connection column 111, so as to fix the inner bracket 2 in the placement cavity 11. In this embodiment, the inner bracket 2 is firmly installed in the placement cavity 11 through precise thread matching. The tight engagement between the threaded connection column 111 and the threaded countersunk hole 251 not only provides sufficient connection strength, but also effectively prevents the inner bracket 2 from loosening or displacement during use, thereby ensuring the stability and reliability of the overall structure of the charging dock.

In this embodiment, by carefully setting the display fixing groove 14 and the heat dissipation groove 15 on one side of the housing 1, efficient integration of functionality and heat dissipation performance is achieved. The display fixing groove 14 accurately positions and firmly fixes the interactive module 6, ensuring stable display and smooth interaction of the user interface, greatly improving the user experience. At the same time, the heat dissipation groove 15 directly corresponds to the main control module 5, and effectively performs heat dissipation management for its high-heat area. Through the through groove 221 set in the first fixing area 22 and the heat transfer sheet 222 inside it, one side of the main control module 5 is closely fitted with the inner wall surface of the heat dissipation groove 15. This design not only greatly increases the heat conduction area, but also significantly improves the heat transfer efficiency, so that the heat generated by the main control module 5 during operation can be quickly and effectively dissipated through the heat dissipation groove 15. In this embodiment, a three-dimensional stacking architecture consisting of multiple groups of GaN chips is adopted. This design greatly improves the power density, so that the charging dock can provide efficient and stable power output in a compact space. By driving multiple parallel charging channels on the first connection unit 7 or the second connection unit 8, the module effectively meets the needs of charging multiple devices at the same time, improving the user's convenience. The line voltage crossing technology implemented by the main control module 5, especially the laterally arranged gallium nitride switch array it contains, realizes multi-channel zero voltage switching. This feature not only reduces energy loss, but also significantly improves the response speed and stability of the system. The graphene layer or aluminum nitride composite thermal conductive layer covering the surface of each GaN chip effectively improves the heat conduction efficiency, ensures the stable operation of the chip at high power output, and extends the service life of the device. In addition, the introduction of the dynamic resonant compensation circuit enables the system to adaptively match parasitic parameters within the 10-120W power range, further optimizing power transmission efficiency, reducing harmonic interference, and improving the electromagnetic compatibility of the overall system.

[0034] The first end cap 3 is provided with a first fastening member 31, and the second end cap 4 is provided with a second fastening member 41.

At the same time, the second end cap 4 is uniquely designed, integrating the second fastening member 41 and the connecting wire 42, wherein the second fastening member 41 also ensures the stable connection between the end cap and the placement cavity 11, forming a symmetrical layout with the first end cap 3, and enhancing the overall structural stability of the docking station. The setting of the connecting line 42 is even more ingenious. One end of the connecting line 42 is electrically connected to the main control module 5, providing a necessary power transmission path for the multi-port charging function of the expansion dock, ensuring that the power supply of each charging port is stable and efficient.
